It is known from Volume 20, No. 2, pages 62 to 68. In the known method, the traveling section is obtained from the total number of rotations of the left and right wheels, and the traveling angle is obtained from the difference between the number of rotations of the left and right wheels. In that case, it has been found that errors occur, especially when measuring the running angle. These mistakes can occur if there is a large distance or gap between each city station, or if the driver deviates from a given route and as a result does not arrive at one city station for a relatively long time. It cannot be ignored. To give the driver instructions to ensure that he can reach his desired goal reliably and quickly, due to the additional error in the angle values of the position-measuring method and the navigation method independent of the vehicle. Is no longer possible.

要な値として、車両のトレツドbがある。The method of measuring the position of a land vehicle by the combined operation of the planimeter system has been known for a long time. In this regard, refer to the prior art mentioned at the beginning. The distance traveled and the direction of travel are determined in a known manner by detecting and evaluating the rotational speed or the rotational state of the wheels of the axle, which are preferably not driven. The pulse generator provided on each wheel of the axle that is not driven generates a pulse every time the wheel rotates. These pulses are counted by the position measuring system and from these pulses the change in position of the vehicle is calculated. For example, if the vehicle travels from location 1 to location 2 as shown in FIG. Required by. In this equation, Z R is the number of pulses taken from the right wheel and Z L is the number of pulses taken from the left wheel. Z represents the number of pulses for each wheel and rotation, and U represents the circumference of the tire. The driving angle is an equation Calculated by Another important value in this equation is the vehicle b b.

から一定値Kを求めかつ走行角度の補正に用いることが
できる。In the case of a curve run, the tread b assumed to be constant in the second equation is no longer constant. This is because the contact surfaces of the tires of the vehicle are relatively deviated from each other depending on the traveling speed when traveling on a curve. This causes an error in the pulse number difference Z R -Z L , which results in
Positioning errors occur. Such an error can be eliminated by correcting the calculated traveling angle with the value K. This value K is usually in the range of 0.5 to 2 and is a coefficient that depends on the speed of the vehicle and the radius of the curve. This value therefore depends on the lateral forces acting on the vehicle. The speed of the vehicle and the curve radius of the vehicle can be measured by means of the values already determined. The difference Z R -Z L in the measured pulse numbers is then inversely proportional to the radius of the curve, whereas the total measured pulse number is proportional to the radius of the curve. The speed is defined by the total number of pulses and the running time until the predetermined total number of pulses is reached. A constant value K can be obtained from these values and used for correcting the traveling angle.

る。In the present invention, error correction is performed as follows. That is,
The difference in the measured number of pulses is replaced with the correction value. This correction value is selected depending on the vehicle speed and the radius of the curve as described above. The vehicle speed is calculated from the total number of pulses and the time taken to reach that total. Also,
The curve radius is obtained from the total number of pulses and the difference in the number of pulses. That is, the correction value is obtained based on the sum of the rotation speeds of the two wheels, the difference between the rotation speeds of the two wheels, and the time required for the wheel rotations to reach a predetermined number.
求められた補正値は、車両の型式に依存する。The calculated correction value depends on the type of vehicle.

It is processed in the transmitter evaluation circuit 8. As a result, these pulses can be easily processed by the microprocessor 10. The processing by the microprocessor is performed by the program filed in the program ROM 11. The RAM 12 is used in this connection for storing data, for example the driving direction and the driving distance calculated by the microprocessor. The direction of travel and the distance traveled are then determined, for example, by the equations mentioned at the beginning. A timer 13 is used to measure the running time. The error correction is performed by using the value included in the three-dimensional correction matrix instead of the difference Z R -Z L of the measured pulse numbers. This three-dimensional correction matrix is stored in the matrix ROM 14. The respective matrix element is selected on the basis of the difference in the number of pulses measured between the two wheels and the total number of pulses and the time taken to detect that the total number of pulses has been reached. . This time is counted by the timer 13.

る。Depending on these three values, the corresponding matrix element is called and the value K is assigned to this matrix element. Now you can get the correct running angle. At that time, the traveling angle calculated first is corrected by the coefficient K. The more advantageously, this correction, instead of the value Z R -Z L, matrix ROM1
This is done by using the new value taken from 4.

して補正することが可能となる。The matrix elements are empirically determined in driving tests or calculated on the basis of different types of vehicles, traction devices and wheels. The correction of errors using the matrix ROM makes it possible to use the position measuring device in all vehicles. For various vehicle types, it is only necessary to choose a matrix ROM which is adapted to the corresponding vehicle type. This makes it possible to correct the position measurement error depending on the traveling speed and the variability in the curve when traveling on a curve.
